EXHILARATOR FOR COMBUSTION-'EN GINES.

Application filed June 2, 1915.

To all whom t may eonoern Be it known that we, HENRY P. Mnn'rnn, a subject of the Emperor of Austria-Hungary, and Erin'. llln'sniinin, a citizen ot the United States, and residents. respectively, of Homestead and Nest Hoboken, in the county of Hudson and State of New Jersey, have invented a new and l'mproved EX- hilarator for oinbnstion-Engines, of which the following a 1full, clear, and exact de.- scription.

Among the principal objects which the present invention hes in view are: to provide Ineens for admitting atmospheric air 4to the mziniold of engine ot' the character mentioned and intermediate the eXplosion chambers and carbureter thereof, for increasing at will the air content of the fuel charge; to provide means for manually varying and controlling the proportion of air included in the charge; to provide means for controlling the proportion in the inanner mentioned in positiwn convenient for the operator; and to provide. means for sipating the effect o" a back lire of engine.

Drafwo'a-gef-Figure is a. side view of an engine of the character mentioned, showiilg in conjunction therewith, carburetor, manifold and exhileretor, constructed and arranged in accordance with the present invention; Fig. 2 is a detail view on an enlarged scale of the exliila rator control box, part of the Wall of the dissipating casing thereof being out away; Fig. 3 is a section thereof, teken as on the line in Fig, *2; and Fig. 4 is a detail View on an enlarged scale, showing the outer dissipating casing.

Desoriptz'orf--As seen in the drawings, the exhilarator is provided with a control box 9, which] may be clamped to the steering post 10 et an automobile by a suitable clamp. The clamp shown Iin the drawings, is a collar section ll, formed integrally with the base of the box 9, bolting brackets l2 being extended therefrom, to receive the bolts 13. The brackets l2 correspond with brackets 14 of a collar sect-ion l5, through. which the said bolts are also passed. When the two sections are drawn by the manipulation of the screw nuts 1.6 on the steering post 10, the,box 9 is held rigidly in service position.

The box 9 is maintained in open commusuitable the Specification of Letters Patent.

serial No. 31,6134.

Flexible pipe l. The pipe 18 iffornied of rubber is held on the groo'fed nipple ll), with which the box 9 is furnished, The communication thus established between the box 9 and manifold 17, results in admitting air o said manifold when the sinne is admitted to the box. This result arises when the valve 2O is lifted from the seat formed therefor in the partition 21, dividing the box 9 into an inner supply and outer distrilniting section 22. The side Wall o the distributing section. is pierced to forni a series of' perorations 23, tlirougli which air is admitted to the dis yrilniting section but by which the hot or flaming gar-es are partly dissipated in the event ot' a back fire occurring in the engine. The air thus supplied to the section is drawn trom un annular chamber 24 formed by the dissipating casinr 25, as best seen in Fig. 3 of the drawings.

The easing 25 is held on the box 9 b v screw bolts 26, the threaded portions of said bolts engaging tapped perfor-ations formed in the partition 2l., as shown best in Fig. 3 of the dravings. The casing 25 forms the top or cover of the section 22 and chamber It forms the bottoni of the chamber Q4, having to this end, an inturned flange 27. The ilenfe 2T furnished with a. multiplicity or small perforations 28. When air is beingedinittcd into the box 9 through the tiro sets oi' peri'orations Q8 and 23, the arrangement referred to avoids any Whistling or sucking sound. lvlien, however, due to a bar-l; lire,` hot or flaming `gases are forced outward from the bos 9, through the section 22 and chamber 24, the gases are split up into a, numbei` of relatively harmless jets, which become extinguished immediately on passing the relatively-small perfforations 28. The valve 20 is moved to and itrdrlll its seat by manipulating a screw 29, said Screw being provided with a knurled head 30 eX- tending beyond the casing and in position convenient to the hand of the driver of the automobile on which the exhilarator is installed.

Opemzonr-fwhen in service, the exhilarator is operated as follows: lll-hen the m0- tor is started, the screw and head 30 thereof are manipulated to seat the 'valve 20. In this condition, the fuel delivered by the carbureter with which the said motor is equipped, is unaltered. llben in the operation of the automobile. the motor is -workllO ing smoothly, the driver manipulates the screw 29 to lift the valve 20 from its seat. The air from the section :22 is 'permitted to be drawn through the pipe 18 to the manifold 17 and from thence into the cylinders of the motor. The air thus introduced is added to the fuel delivered by the carbureter. This results in a considerable saving in the explosive fuel consumed. If the in1 poverishment of the fuel which results from the admission of atmospheric air be too great, this ma)7 be immediately corrected by Athe manipulation of the screw 29.

Claims:

l. An apparatus as characterized comprising a supplyv pipe. for introducing air to the manifold of an explosive engine; a supply casing.: therefor having a distributingr section and a partition embodying a valve seat separatinpr said section and pipe; a manually-manipulated valve for varying the opening of said valve seat; and a dissipating casingv encirclingr said distributing?r section and having an edge opening to be turned from the operator when the apparatus is in service.

An apparatus as characterized coma prising a supply pipe for introducing air to opening of said valve seat; means embody` ing a screw directly connected with said valve for adjusting the same; and a dissipating casing surroundir f said distributing section for forming a esipating chamber annular-ly disposed reference to said section, said chamber mbodying a Se- 40 ries of perforations communicating with said chamber and section and with said chamber and the surrounding air. l

I. An apparatus as chareo'gterizedY comprisinpr a supply pipe for introducing air to45 the manifold of an explosive engine; a supply casing therefor having a distributing section and a partition embodying a valve seat separating said section vand pipe; a maniwily-manipulated valve for varyingthe opening of said valve seat; and a chamber annularly disposed with reference to said section, said chamber embodying a seriesv of perforations communicating with said chamber and section and a Second series of perforations communicating with said cha rnber and the surrounding air.
